There is a LS1028A eval board in kernelci here:
https://lavalab.nxp.com/scheduler/job/170566
I actually have this board which also have a LS1028A SoC:
https://lavalab.kontron.com/scheduler/job/1771
But in the latter you won't see much because earlycon isn't active. [I'm
about to fix that.]
By reverting patch 1/5, the board will work again.

There is a LS1028A eval board in kernelci here:
https://lavalab.nxp.com/scheduler/job/170566
I actually have this board which also have a LS1028A SoC:
https://lavalab.kontron.com/scheduler/job/1771
But in the latter you won't see much because earlycon isn't active. [I'm
about to fix that.]
By reverting patch 1/5, the board will work again.

There is a LS1028A eval board in kernelci here:
https://lavalab.nxp.com/scheduler/job/170566
I actually have this board which also have a LS1028A SoC:
https://lavalab.kontron.com/scheduler/job/1771
But in the latter you won't see much because earlycon isn't active. [I'm
about to fix that.]
By reverting patch 1/5, the board will work again.
